Answer:
252
Step-by-step explanation:
When it comes to perimeter, the ratio is the same. So, the scale factor of the perimeters in this problem is simply, 3.5. To find the new perimeter, multiply 3.5 by 72 to get 252. :)
Answer: length = 8 units
Width = 2 units
Step-by-step explanation:
Let the length of the rectangle be represented by L
Let the width of the rectangle be represented by W
The sum of 5 times the width of a rectangle and twice its length is 26 units. This means that
5W + 2L = 26 - - - - - - - - 1
The difference of 15 times the width and three times the length is 6 units. It means that
15W - 3L = 6 - - - - - - - - 2
The system equations are equation 1 and equation 2.
Multiplying equation 1 by 3 and equation 2 by 2, it becomes
15W + 6L = 78
30W - 6L = 12
Adding both equations,
45W = 90
W = 90/45 = 2
15W - 3L = 6
15×2 - 3L = 6
-3L = 6 - 30 = - 24
L = - 24/ -3 = 8
Y(2)-y(1)/x(2)-x(1)
(-9)-(-6)=-3
10-1= 9
-3/9=-1/3
answer: -1/3
